The Stow Company
Location: Holland The manufacturing plant at The Stow Company was being affected by persistent leaks in its older standing seam, metal roof system. Heat lose through the roof was causing ice dams at the roof edges and the penetrations in the roof were blocking the flow of water and leaving it with no way to drain off the roof. Langerak Roof Systems was able to eliminate those issues without affecting the day to day operations within the facility. EPS flute filler was installed between the two foot metal ribs to make a smooth, substrate for the roofing system. Doubling the insulation's "R" value will conserve energy with an estimated payoff in 5 1/2 years for the insulation and roof system. Finishing off the perimeter of the roof, a new metal drip edge was installed to match the color of the existing wall panels. Beginning in mid-September, the project was completed before the winter storms hit, so the owner could benefit from the lower utility costs and the elimination of roof leaks that they had experienced in previous years.

Steelcase Wood Plant
Location: Caledonia, MI Completion Date: March, 2001 The Steelcase Wood Plant building is over 600,000 square feet of effiency and beauty, both inside and out. Langerak stayed on schedule despite significant wet weather conditions. This project required, on a daily basis, the installation of 30,000 square feet of roof insulation, tapered saddles, membrane, 90 tons of stone ballast, the required equipment flashings, and concrete walkway pavers to and around the equipment plus the perimiter of the building. This sixteen week installation was installed injury free. This was accomplished though through training and intensive monitoring by our safety officer. The dedication to a safe working environment by our team leaders, continually encouraged the rest of the team toward this goal.
Haworth Corporate Office
A spectacular transformation occurred at Haworth in Holland, Michigan with the renovation of their office facility and the addition of the Haworth Center, earning lead accreditation. Catching your eye as you arive at the facility is the 49,100 square foot vegetative roof covering on the Haworth Center. The original specification was a hot fluid applied roof system with a "conventional" vegetative roof covering, but, due to the steep slope, erosion of the growth media was a concern. After consultation, the owner decided on an EPDM roof system, using LiveRoof module plant containers as ballast. This would minimize possible erosion and provide the owner with an "instant" green roof. Installation of the roof included placing sound deadening batt system in the Epicore acoustical deck. Over this, three inches of rigid roof insulation, providing an R-value of 21.1,* were mechanically fastened. A Firestone 60 mil EPDM fully adhered membrane was installed to provide a watertight enclosure so interior construction could continue while the LiveRoof plants matured. A firestone 45 mil EPDM protection sheet was installed for the 21,226 LiveRoof modules to be placed on, ensuring additional protection for the roof membrane. The installed modules were construced of recycled plastic, much of which came from Haworth itself. The modules contain eleven varieties of sedum, chosen by the owner for their "evergreen" color, fine texture, low growth height, and minimal maintenance. A highly skilled labor force kept the project on schedule, allowing the interior trades to work in weather proof conditions.

Aquinata Hall Renovation
Location: Grand Rapids Completion Date: October 2012 Constructed in 1966, Aquinata Hall was typical of the buildings of that era. Roof areas were flat with ponding water and some of the roofs had the original built-up asphalt roof buried beneath newer roofs which had been installed over the years. Under the supervision of Erhardt Construction, Langerak Roof Systems was contracted to remove the existing roofs, down to the deck, and install a new fully adhered 60 mil. Firestone TPO Roof System. The new roof includes two layers of polyisocyanurate roof insulation to bring the "R" values up to current standards. Sandwiched between the polyisocyanurate is a layer of expanded polystyrene insulation, up to 8" thick, cut to form slope and saddles, creating positive drainage to the existing drain system. In addition, new canopies and cornices were added, at areas around the perimeter, to give a modern and elegant appearance to the building. The project also involved the flashing of new air handling equipment which included curbs installed horizontally, over the roof deck, and vertically, on the walls. Much of the work on the perimeter also involved working on narrow ledges or shelves where installers were constantly tied off for their protection. Adding a finishing touch to the roof system, a Firestone Una-Clad metal flashing system was installed at the perimeter, creating an appealing transition from the roof to the building's new EFIS system.
